HADEF 46/21E Installation, Operating And Maintenance Instruction page 9

▫
Electronic overload protection for units up to 1000 kg available as option.
The overload protection is adjusted by the manufacturer according to the regulations that apply. The
overload protection prevents lifting a load that is too heavy by switching off the hoisting motor. When putting
the winch into operation or after current of the winch has been cut off or after the overload protection has
operated, press the button "lowering" shortly to re-activate the relay. A re-adjustment i.e. for maintenance
reasons is possible.
DANGER!
The overload protection serves exclusively to protect against damage to the device due to overloading
when moving loads. Its function must not be integrated into the operational work process!
 Control
▫
Low voltage control (direct control depends on the kind of unit)
▫
Indirect control with phase sequence relay. The phases must be exchanged if the turning direction is
wrong.
▫
Units with limit switch are fitted with low voltage control.
▫
Radio control is available as option.
 Control switch
▫
Control switch suitable for single hand use.
▫
The control switch housing is made of shock- and fracture-proof plastic.
▫
The control cable is fitted with stress-relief rope (not applicable for radio control).
▫
2 step buttons for 2 wire rope speeds
 Phase sequence monitoring relay
All devices with low voltage control are equipped with a phase sequence and phase failure monitoring relay
as a standard. This will prevent incorrect phase sequence when connecting to the mains supply and will
switch off the device if phase failure occurs. In addition, all devices with low voltage control are equipped
with thermal sensors to protect the lifting motor and end switches for lifting/lowering as a standard.
 Overheat protection electric motor

Thermocouple´ PTC thermistor with tripping device
 Pressure roller (as option)
The pressure roller prevents the skipping of rope
windings, when the unloaded rope will on- or

The respective rope
functionally correct .
 Slack rope switch (as option)
Avoids slack rope when the rope is uncharged
 Rope guiding device (Optional)
The type mentioned in these instructions serves as example. Other versions are possible.
For correct positioning of the wire rope on the
rope drum.
An automatic stopping mechanism (limit switch)
for the winch is installed, in case of tearing of one
of the roller chains.
